yong yan » yang yang, dong yang, ying yang
yun gain » you gain, n gain, yun hin
run gain » run pain
gang hai » dang hai, shang hai, eang hay
yang xi » yang di, yang jui
yang yi » yang di, yang jui

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: wang yong yan ((yun gain) OR (run gain)) ((yang xi) OR (yang yi)) gang hai ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yong yan ((yun gain) or (run gain)) ((yang xi) OR (yang yi)) gang hai ;*".
